19 The error code returned by ERR_get_error() consists of a library
20 number, function code and reason code. ERR_GET_LIB(), ERR_GET_FUNC()
21 and ERR_GET_REASON() can be used to extract these.
22
23 The library number and function code describe where the error occurred,
24 the reason code is the information about what went wrong.
25
26 Each sub-library of OpenSSL has a unique library number; function and
27 reason codes are unique within each sub-library. Note that different
28 libraries may use the same value to signal different functions and
29 reasons.
30
31 ERR_R_... reason codes such as ERR_R_MALLOC_FAILURE are globally
32 unique. However, when checking for sub-library specific reason codes,
33 be sure to also compare the library number.
34
35 ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are macros.

38 The library number, function code and reason code respectively.
